Usage Guidelines
•
Use the no form of this command to clear an NTP server from the list of configured servers.
•
To configure NTP in the client mode you must first define the NTP servers. Up to 3 NTP servers may
be defined.
•
Either an IP address or domain name for the specified server can be entered.
•
The NTP key identification is an integer. It corresponds to an MD5 authentication key contained in an
authentication file (.txt) located on the server. This file must be on both the server and the local switch,
and match, for authentication to work. Enter the key identification using the key keyword if the server
is set to MD5 authentication.

It specifies the minimum polling interval for NTP message. This number
is determined by raising 2 to the power of the number entered. There-
fore, if 4 were entered, the minimum poll time would be 16 seconds (2
= 16).The maximum poll interval is fixed at 10 (1,024 s). The minimum
poll interval defaults to 6 (64 s), but can be decreased by the minpoll
option to a lower limit of 4 (16 s), or increase to the maximum limit of
10.
